PAPER-RETAINING DEVICE.

To all whom it may cortcern: 'Be it known that I, GEORGE W. DONNING, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements-in Paper-Retain ing Devices; and I do hereby declare the following to be a full, clear, 'and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a marginal clamp for holding Work on a fiat platen, such as is used in that class of typewriters known as book or commercial type-writers. v

A furtherobject of the invention is toprovide in such a clamp means for supporting it independent of the platen and means for elevating it away from the platen to ermit the platen to. be tilted without inter erence with the clamp.

Another object is to provide means for securing the clamp so that the track-frame may be shifted longitudinally without disturbin the clamps.

ith these and other objects in view my inventioncomprehends the construction, ar-

rangement, and combinations of arts, as

hereinafter more claimed,

spring. Fig. 11 is an enlarged fragmentary view showin the position of the parts relative to the p aten. Fig. 12 is another view of one of the blades. Fi 13 is a .view of the spring for tensioning t e blade, and Fig. 14 is a view in side elevation of the device for tilting the blade and for holding it in position.

In the drawings, and referring particularly to Figs. 1 to 9, inclusive, A designates the platen, which in this instance is flat and which may be secured to a table in any pre-- ferred manner, though in this instance I have illustrated it as'hinged, so that it may be tilted When desired and as shown in Fig. 1 of the drawings. Disposed contiguous to the laten and surrounding it is a suitable trackilame A which in this instance is preferably capable of slight longitudinal movement b reason of being slidably mounted, as wil presently be described. It will be obvious that any suitable'means may be provided for effecting adjustment of the frame or.that such adjustment might even be effected by merely pushing the frame-back and .forth.

An adjusting-screw may be located at the front of the frame, as disclosed in my co end-' ing application, Serial No. 142,790, file February 10, 1903, and such a screw has been merely indicated at Ain the accom anying drawings. Disposed preferably para lel with the left-hand member of the frameA is a shaft B, which maybe mounted on the frame,

mounted upon any other suitable part of the machine. Upon the rod or shaft B are disposed 'one or more blades C, which may be secured to or connected with the shaft in any preferred manner so long as they are arranged to bear upon the upper surface of the platen when the platen is in its normal position. The forward end of the rod B is in this instance preferably mounted on the forward member of the track-frame in a journalblock hereinafter more'fully described. The rear end of the shaft B is mounted in a bracket 1), Fig. 1, preferably secured upon the tilting element D of the support member Dof the adjacent track. Said support member is provided with longitudinal slots (1 which receive headed pins d, depending from the track-rail, whereby sliding of the track upon its support is provided for.

, as shown in Figs. 1 and 2, or be secured to or forward endof the rod is disposed in themember of the track-frame A In the jourjournal-box E, mounted on the forward The lever H fits on the bolt at this portion and against the head.F as shown in Fig. 4, and is thus prevented from turnin on the bolt by the said registering irre u ar contours. The bolt is, as.stated, tu ular and the rear end of the rod B is disposed in the bore of the bolt, as clearly shown in'dotted lines in Fig. 2, and is ca able of sliding there in. The neck portion F of the bolt projects beyond the journal-block E, and the bolt is retained in the block b a washer K, secured pn thisknecli. ghpl was er is rovit}1 ug or ey w '0 projects t on o enin F in neck portion F and slides in tire k eywag b in the shaft B to permit the backward and forward movement of the'track-frame on the shaft and at the same time to maintain the shaft in normal osition, so that theforward end of the shaft B has a sliding movement in the'bore of the bolt F, but may be rotated therewith by the key or rojection k on aging a groove 1) in'the shaft B, in whic 1t slides when theshaft reciprocates in its bore. On the shaft B ,is secured one or a series of blades or plates 0, these being 'arranged onthe shaft and the shaft being so disposed relative to the normal position of the platen that the blades will bear onthe platen at a,

'slight angle. The blades have preferably one or more stop-pins c, that form abutmentpoints for the sheet or sheets that are inserted under the clamp when the'same is raised. A coiled spring B Fig. 2, is wound around-the shaft both at the forward and rear ends thereof and has one of its ends enga ing theis so wound a's'to retain the blades normally upon the surface of the platen, and against the force of this tension device, com rising the spring, the shaft may be rocked the lever H, serving to raise the blades an permit the insertion of the sheet and which may then be ti htly clamped upon the platen when the b ades are lowered to contact with the sheet. To retain the blades in one or more of their raised positions, the lever H is provided with notches or lugs h h, Fig. 3, that are engaged by a (pawl H which may be pgovided wit a ham le H for moving the same when desired. When the lever H is with a.

turned a short distanceto raise the blades, the pawl II will, b gravity, fall into the notch h and, u on the ever being released, the lever and t eshaft will be retained in this position. After the paper has been inserted the-pawl ma be moved out of the notch by moving the andle H of the pawl H the pawl being fulcrumed at H With this construction, as will readily be understood, it is possible to raise theclamp slightly and lock it in that position temporarily and then by operating the pawl H permit the blade again to contact with the platen and be retained there under the action of the sprin B If, however, it is desired to raise the 0 amp still higher, as for permitting the platen to be tilted; the lever H is operated to cause the shaft B to be still further rotated to bring the notch k of the lever H into on a eme'nt with the pawl, which willthen lock 1t in that position until "released, as already described.

When the track-frame is adjusted longitudinall by means of the adjusting-screw A, as a ready referred to, the shaft B will remain stationary and movement of .tne journal-block E upon the shaft B will permit the adjustment of the track-frame 1ongitu. dinally without disturbing the shaft, and thus the blades C. This is an im ortant feature, since it is often desirable, a' er the writing-sheet has been secured to the platen, to adjust the, track-frame longitudinally to position the writing mechanism, which is sup orted on the track-frame intermediate of t e regular line-s acing, asfully disclosed in -my concurrent y pending application, Serial No. 142,790, referred to.

In Figs. 10 to 13, inclusive, I have illustrated a modified form ofconstruction, the modification residing in roviding each blade C with a spring in ad ition to the springs disposed upon the shaft B at each end, as in the construction already described. In the modification I have illustrated the rod B as supported in blocks-dis osed upon \he platen in lieu of disposing t em upon the trackframe, as inthe construction illustrated in Fig. 1. In the form-of device illustrated in Fig.10 the shaft B is provided with the roove b and operates at the rearin the racket b and at the front in the journalblock E. Each blade is referably provided with a spring B each en of which takes into slots 0 in the walls of an opening 0 in the blade and also .in the groove 1) of the shaft B, the spring being provided with-a central projecting ortion B, which bears centrally upon the b ade, as illustrated in Fig. 11. In

rotated all of the blades may be lifted to raise them up fromthe surface of the platen.

In Fig. 14 is illustrated a modification of the operating-lever and retaining device therefor. In this construction the lever H for operating the shaft is provided with notches h k and h" upon its inner curved end, Fig. 14, and these are to be engaged by a roller B upon the spring-arm B secured in any preferred manner upon the platen, so that it will be in operative relation-with the lever H.

B to ride over the notch 71; into the notch k or into,the notch h according to theheight to which the blades are to be raised. The' springs'C at the ends of the rod or the shaft B have one of their ends engaging the groove b and are coiled around the shaft, and the other end bears upon the platen, so that when the shaft B is rotated the spring'is placed under tension to force the blades back upon the platen when the arm B" is moved to release the roller B from engagement with the notches k or it in the lever H By this construction the blades C are each forced against the platen with a yielding pressure, which will compensate for any distortion of the platen or shaftwhich would alter their parallelism or any unevenness of the surface of the platen; but when the shaft is rocked after the slight tension'of the blades is released the blades will be raised from the platen on the shaft B and the paper nlay then be inserted. Since the tendency of the several blade-s rings may cause the shaft to buckle upwar I provide guide-plates B secured to an convenient part of the machine, as to the track-frame, having bent parts that engage the upper surface of theshaft, as shown in Fig. 10.
